Initial plant list was based on our survey, mostly of eastern part of Tidmarsh performed from September 2011 to September 2017 as shown in a map here. This list contains current data including adjacent Beaver Brook Conservation area. It uses newer plant classification with simplified hierarchy (as in MA County Checklist first edition). The list was generated using three tables: salicicola photos, explicit Tidmarsh records and generic records from Tidmarsh bounding box which includes verified observations from iNaturalist.org (e.g., Cabomba caroliniana misidentified as Ranunculus aquatilis, or Barbarea vulgaris). Total, 641 species with 6,035 image- and 450 other records are incorporated; it does not include records of yet not properly identified plants but includes photos of some "garden plants" (e.g., Betula nigra, Stewartia, Bistorta, Clematis terniflora, at least the latter is an invasive plant and should be monitored or removed). The treatment of the invasive willow is here more detailed and includes records of putative hybrids.

The line below each plant species name shows metadata from County Checklist, including county distribution for the entire state. and when necessary additional notes. Every plant family and genus is anchored, i.e., for faster navigation one may append their name at the end of URL, e.g., #Asteraceae, for Aster family.
